EXAM QUESTIONS
QUESTION 1
Which of the following structures is located in the alveolar processes?
A. Teeth
B. Villi
C. Sinuses
D. Tonsils
CORRECT ANSWER
Teeth The teeth are located in the sockets of the alveolar processes of the mandible and maxillae.
RATIONALE: The correct answer is "A. Teeth" because the alveolar processes of the mandible and maxillae are the bony
ridges that house the tooth sockets, providing a stable foundation for the teeth to erupt and anchor in place. This
structural relationship between the teeth and alveolar processes is fundamental to dental anatomy and oral health.

, QUESTION 2
What is the wound classification for a bronchoscopy?
A. Clean
B. Contaminated
C. Dirty and infected
D. Clean-contaminated
CORRECT ANSWER
Clean-contaminated
RATIONALE: During a bronchoscopy, the airway is entered but not entered into a part of the respiratory tract that
normally contains flora, implying that the procedure inherently involves some risk of contamination. However, this risk is
generally lower than in cases where the procedure involves entering an area with normal flora, thus making "Clean-
contaminated" the most appropriate classification.
QUESTION 3
The enzyme used to soften the zonules of the lens before cataract surgery is:
A. Atropine sulfate
B. Alpha-chymotrypsin
C. Acetylcholine chloride
D. Pilocarpine hydrochloride
CORRECT ANSWER
Alpha-chymotrypsin
RATIONALE: Alpha-chymotrypsin is used to soften the zonules of the lens because it is a proteolytic enzyme that breaks
down the proteins holding the zonules together, allowing for safe and gentle removal of the cloudy lens during cataract
surgery. This enzyme's ability to dissolve the protein-based zonules makes it the ideal choice for this specific step in the
surgical process.
QUESTION 4
How should the stretcher be oriented when necessary to use an elevator to transport a patient to the
OR?
A. Place stretcher sideways in elevator
B. Enter head first, exit feet first
C. Position in elevant is irrelevant
D. Enter feet first, exit head first
CORRECT ANSWER
Enter head first, exit feet first
RATIONALE: When transporting a patient in an elevator, it's essential to maintain control and prevent falls or injury,
which is achieved by entering with the head first and exiting with the feet first, allowing for a more stable and secure
transfer. This orientation also enables the stretcher to be stabilized in the elevator with the head closest to the control
panel, providing a safe and controlled environment for transportation.

, QUESTION 5
Which of the following is a curved, transverse incision across the lower abdomen frequently used in
gynecological surgery?
A. Midline
B. Paramedian
C. McBurney's
D. Pfannenstiel
CORRECT ANSWER
Pfannenstiel
RATIONALE: The Pfannenstiel incision is the correct answer because it is a type of curved, transverse incision
specifically designed for lower abdominal access, which is ideal for gynecological surgery due to the location of female
reproductive organs. This incision provides a wider range of exposure and easier access to the pelvic cavity compared to
other types of incisions listed.
QUESTION 6
When perforated metal trays are placed on the shelves of the steam sterilizing cart, they should be
positioned how?
A. Flat
B. Upside down
C. Vertical
D. Angled
CORRECT ANSWER
Flat
RATIONALE: Perforated metal trays should be positioned flat to prevent water from accumulating in the perforations
and causing uneven heating or moisture buildup during the steam sterilization process. This positioning ensures that the
trays are exposed to consistent and even steam flow, thereby facilitating effective sterilization.
QUESTION 7
Hyperkalemia is a high concentration of:
A. Calcium
B. Nitrogen
C. Potassium
D. Albumin
CORRECT ANSWER
Potassium
RATIONALE: Hyperkalemia is a medical condition characterized by an elevated level of a specific electrolyte in the
blood, which is crucial for maintaining proper muscle and nerve function. The electrolyte in question is potassium, as its
imbalance can lead to serious cardiovascular and neuromuscular complications.
QUESTION 8

, Which of the following tissues are cut using curved Mayo scissors?
A. Fascia
B. Periosteum
C. Dura mater
D. Arterial wall
CORRECT ANSWER
Fascia
RATIONALE: Fascia is typically cut using curved Mayo scissors because it is a dense, fibrous connective tissue that
requires a sharp, precise cut, which curved Mayo scissors are well-suited to provide. In contrast, the other options -
periosteum, dura mater, and arterial wall - have different tissue characteristics that may require different types of
scissors or cutting techniques.
QUESTION 9
What laser beam can travel through clear tissues without heating them?
A. Argon
B. Excimer
C. Carbon dioxide
D. Neodymium: YAG
CORRECT ANSWER
Argon
RATIONALE: The key concept here is that the laser beam must have a wavelength that is strongly absorbed by water or
hemoglobin in tissues, preventing it from heating them. This property is most closely associated with the Excimer laser,
which has a wavelength that is highly absorbed by these substances, allowing it to cut through clear tissues without
heating them.
QUESTION 10
Permission for treatment given with full knowledge of the risks is a/an:
A. Tort
B. Malpractice
C. Personal liability
D. Informed Consent
CORRECT ANSWER
Informed Consent
RATIONALE: "Informed Consent" correctly encapsulates the concept of permission for treatment given with full
knowledge of the risks because it involves a patient having complete awareness of the potential consequences and
making an educated decision about their care. This informed decision-making process is a fundamental aspect of
medical ethics and law, prioritizing the patient's autonomy and well-being.
